Yet another e-toll billing complaint

I have wrongly been billed for another person's vehicle, just like happened to so many other people. (Just read all the Hello Peter complaints). Notwithstanding so many complaints about the incorrect billing, SANRAL show a callous disregard for inconveniences caused, and a unwillingness to take responsibility for their incompetence. I have sent detailed correspondence to SANRAL about my specific complaint, yet got a standardised e-mail back saying that I should provide them with a affidavit amongst other things. The aforesaid e-mail that is being sent out, is contrarary to South African law, as the onus of proof lies with SANRAL. Thus, not surprisingly, SANRAL also shows a disregard for the laws of the country in which they operate. SANRAL, sort out your mess.
